Built for hosts recognizing 10GB-LRM-SFPP, this HT-manufactured SFP+ module delivers 10G transmission at 1310nm. Its rated reach is 220m on OM3 / 300m on SMF, with Duplex LC as the physical interface. The specifications and engineering guidance below support mixed-vendor networks document the correct compatibility identity at each host, while keeping HT manufacture separate from the OEM cross-reference.

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The Duplex LC interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.
Before deployment, check the host port type, supported data rate and firmware requirements. The 10G interface configuration must match the remote equipment; sharing a SFP+ housing alone does not make two transceiver types interoperable.
For this multimode module, confirm fiber grade, modal bandwidth and total loss before commissioning. The 220m on OM3 / 300m on SMF figure applies only under suitable cabling conditions. Inspect every Duplex LC mating point and match the remote optical standard.
For this model, the specified transmit-power range is -6.5~0.5dBm; receiver sensitivity is < -8.4dBm. A sound acceptance record includes link state, diagnostic temperature, supply voltage and transmit or receive levels where the host exposes them. Compare the readings with the stated ranges rather than treating any received light as proof of adequate margin. Persistent alarms or borderline values should trigger an end-face and complete-channel inspection. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.
A mixed-vendor optical link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether both ends use the same wavelength plan and optical standard. Related links locate equivalent hardware, but brand-specific identification must still be selected independently. For this model, the principal parameters are data rate 10Gbps, wavelength 1310nm, rated reach 220m on OM3 / 300m on SMF.
The module is checked for host recognition as 10GB-LRM-SFPP, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.
Quote HT part number SFP-10GLRM-31 together with OEM reference 10GB-LRM-SFPP and quantity. Add the host model and software release when pre-order verification is required. Neutral labels, customer packaging and project-specific compatibility review are available on request.
Quality control covers the optical or electrical interface, host identification and operating link. The verified unit is then individually protected and cartoned. Customer references, rack groups and project packing lists can be added for volume orders.
No. It is an HT-manufactured compatible alternative for equipment that specifies 10GB-LRM-SFPP, not an original Extreme Networks-branded module.
Use Duplex LC with MMF/SMF. The specified maximum reach is 220m on OM3 / 300m on SMF, subject to fiber quality and total link loss.
Only when the two ends share the same optical standard, wavelength plan and supported data rate. Check the exact part numbers and link budget rather than relying only on the module form factor.
Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
